摘要
采用实验法、数理统计法和比较分析法,对3种颜色、4种不同观察状态下人体双眼的闪光融合频率(CFF)进行研究.结果表明:颜色因素、原地站立观察和放音乐时观察对双眼的CFF有显著影响,客观上会造成竞走执裁时的不公允;停止放音乐和走动几步后观察会削弱这种影响.建议竞走比赛时停止播放音乐,同时裁判员在自己负责的区域内适当走动,以提高执裁水平.
Based on test, mathematical statistics and comparative analysis, the CFF of eyes in different colors and observation states are studied. The results show that there exists significant influence to the CFF of eyes in the color factors,the observation states of stationary stand and the broadcasting music, and this can result in impartial judge in judging process. On the contrary, no-mus ic and proper walk can reduce the CFF influence of different observation states. It is suggested that music should be stopped and the race walking judges should walk properly in their charge area during the course of the competition in order to improve the judge level of the race walking judges.
